  • One fifteen-amp fuse
  • Two automotive connector eyelets (5/16" Pigsty)
  • One-mode automotive toggle switch (On/Off)
  • 2 four-inch bolts. (iii/8" diameter). Length of bolts can vary based on the type of light bar and what surface it is existence mounted to. More than bolts may exist needed depending on the bracket way.
  • 1 i-inch bolt (3/8" diameter) (Ground bolt)

  1. i

    Disconnect the battery. You volition need to disconnect both the positive (cerise) and negative (blackness) terminals from the bombardment. Read this wikiHow article for in-depth instructions on how to disconnect the bombardment.

    Warning: Make sure the ignition is off before disconnecting the bombardment.

  2. 2

    Consider the position of the light bar. The light bar can be placed in several different locations.

    Mark holes for bracket installation. The low-cal bar should come up with brackets for the truck. Based on where you want the light bar to be located, take the brackets and hold them in the desired location. Employ a marker to mark where the holes are in the brackets.

    • Don't worry nearly drawing on your truck with the marker, you're going to be drilling holes there so it won't matter in the end.

  4. 4

    Drill the holes. Always wear safety spectacles and gloves while drilling. Insert a 3/eight" drill flake into the drill and drill holes through the frame of the truck where information technology was marked with the marking. Use some form of lubricant to make the drilling easier[citation needed].

  5. 5

    Install the bolts. Place the brackets in the desired location so that it is lined up with the holes. Place the bolts through the holes and put a washer on the dorsum side. Use an adaptable wrench or socket set to tighten the nuts and lock the brackets in place. Place the low-cal bar on the brackets and bolt them together.

  1. i

    Consider where yous want to put the switch. Every vehicle is different and everyone has their own preferences, and then put the switch in a location that suits the specific vehicle being worked on. Look for somewhere that is easy to reach but not in the style and will expect every bit clean or stock as possible.

  2. 2

    Remove the plastic dash panel. After deciding on a location, the next step is to access the back of whatever panel that the switch is beingness installed in. Every panel is different so inquiry the vehicle to run across the specific instructions on how to remove the console. Near panels have like shooting fish in a barrel plastic clips that just need to be depressed to remove the panel. This can exist accomplished with a clip removal tool. The panel may also be held in place with a spiral so a screw driver may besides be needed to remove those.

    • Enquiry your vehicle online or on YouTube to ensure yous're not going to damage anything by trying to do this incorrectly.

  3. 3

    Mark the pigsty for drilling. Now that there is access to the back of the panel information technology should be easier to see where the best location to drill the pigsty for the switch is. Marker that location with a marker.

  4. 4

    Drill a hole in the dash. Drill a pigsty for the switch where the mark is placed, using a drill chip that is but as big every bit the inside diameter of the switch so information technology tin can just barely fit in the hole. This volition ensure a snug fit and prevent the switch from rattling around.

    • If y'all're tossing up between 2 drill bits, choose the smaller i, and exam the fit. You tin can always drill a larger pigsty, simply you can't put it back.

  5. v

    Install the switch from behind the nuance panel. Take the bankroll nut off the switch and place the switch inside the hole that was drilled. Ensure that the side with the bodily switch is facing outward toward the vehicle cab.

  6. six

    Tighten the switch. Once the switch is in identify reattach the nut to secure the switch to the panel.

  1. ane

    Determine where to run the wire. At present that the switch is installed, wait through the vehicle and make up one's mind where the best path for the wire from the low-cal bar to the switch is. Run a wire from near the bombardment through the firewall (the metal wall between the engine bay and vehicle cab) to the switch that was installed. From the switch, the wire will be run to the installed light bar along the vehicle frame and and then up in between the cab and the bed of the vehicle to the low-cal bar. Ensure that the wire will non be in the way of any moving parts of the vehicle.

    • Wherever possible, try and utilize pre-existing holes and follow pre-existing wires.
    • Continue the wire away from the engine, as the heat may cook and ruin the wire.

  2. 2

    Drill any needed holes. Drill any holes that are needed for the wire to be run through any metal (firewall to engine).

    • This step should not exist necessary in most situations, as in that location should already be many wires running through ports in the firewall that y'all tin use.

  3. 3

    Run and secure wire. Run the wire along the path that was determined earlier. Ensure that the wire is secured plenty and then that it won't move simply non so tight that it damages the wire insulation.

    • Use zip-ties if necessary.

  4. iv

    Connect the switch to the wire. After the wire is run to the switch in the cab that was installed earlier, connect the wire from the battery to one screw on the switch. To attach the wire, use the wire strippers to accept off well-nigh ¼" of wire insulation and wrap the bare section of wire effectually the spiral on the switch and tighten the screw until the wire is secured. Repeat the connecting procedure with the cease of the wire that is being run to the light switch from the other screw on the switch.

    • If your switch has three prongs, attach it to the middle one and one of the sides, preferably the 'On' side of the switch (if it's labelled).

  5. 5

    Connect the positive wire to the light bar. Utilise one of the automotive barrel connectors (Crimp/ Heat shrink style) to connect the positive wire to the light bar wire. The carmine wire is the positive.

  6. 6

    Connect the ground wire to the light bar and vehicle. With the positive wire connected to the vehicle, the calorie-free bar will demand a ground wire connected to it. Afterward the positive wire is connected, utilize the remaining automotive barrel connector (Crimp/ Heat shrink manner) to connect the footing wire to the light bar wiring. Black is ground. Find a location to adhere the ground wire to a metal surface on the vehicle. With the location selected cutting the ground wire to the necessary length and take 1 of the automotive connector eyelets (5/sixteen Hole) and crimp them to the other end of the black negative wire. In the location that was selected earlier for the ground wire, drill a hole and secure wire to the metallic surface using the ane ane-inch bolt (5/16" diameter) Tighten the bolt using adjustable wrenches.

    7. Advertizing

  1. 1

    Reinstall the switch panel in the cab. With the switch connected to the wire, reinstall the console that it is attached to by reversing the disassembly process to install the panel.

  2. 2

    Add wire connectors inside the engine bay. The wiring from the engine bay back to the low-cal bar is complete, and then it is time to attach and connect the fuse. The fuse has 2 curt wires connected to it: one tin be continued to the battery and the other is continued to the rest of the wiring. Attach the remaining 5/16 eyelet connector to the end that is connecting to the bombardment. On the remaining finish attach an automotive barrel connector (Crimp/ Heat shrink mode).

    • Brand sure you use a fuse to avoid ruining your calorie-free bar if in that location's a problem with your bombardment or elsewhere in your vehicle'southward electronics.

  3. 3

    Connect the fuse to the wire. Connect the positive wire to the fuse with an automotive butt connector (Crimp/ Heat shrink mode). Attach wire with fuse in a safe location in a way where information technology tin can be attached to the positive end of your vehicle battery.

  4. iv

    Double check your work before connecting to battery. Wait through what has been washed so far and ensure that everything from the light bar to the fuse is connected properly as described.

  5. 5

    Re-connect the battery. Connect the eyelet ending wire from the fuse to the positive final of the battery. Repeat Role 1, Stride i instructions in reverse to reconnect the bombardment.

  6. half-dozen

    Test the light bar. Turn on switch to make sure your light bar is working correctly.
